The Kx Oilless Bushing Sleeve with flange size and made from POM (Polyoxymethylene) is a self-lubricating component designed for superior performance in a range of industrial applications. POM, also known as acetal, is a highly durable and wear-resistant material that offers excellent mechanical properties and stability.
The flange design of this bushing sleeve provides additional support and stability, ensuring a secure fit within the housing. This not only enhances the load-bearing capacity but also contributes to the overall reliability and performance of the bushing.
The self-lubricating nature of POM material significantly reduces the need for external lubrication, simplifying maintenance and extending the service life of the bushing sleeve. This feature is particularly beneficial in applications where regular lubrication is difficult or impractical.
The Kx Oilless Bushing Sleeve is suitable for use in a wide range of machinery and equipment, including pumps, motors, and gearboxes. Its high-quality construction and materials ensure smooth and reliable operation, even under high loads and speeds.
In summary, the Kx Oilless Bushing Sleeve with flange size and made from POM is a robust and reliable component that offers exceptional performance and durability in various industrial settings. Its self-lubricating properties and flange design combine to provide optimal support, stability, and lubrication, making it an ideal choice for demanding applications.
A small amount of lubricant is required for these bushings (All greases or oils designed for lubricating plain bearings). POM bushings have good sliding properties and are suitable for rotary and rocking movements. They have a low coefficient of friction, low sensitivity to edge loading and good damping properties. They can be post-machined. They are low maintenance due to the long relubrication intervals.
This material is designed for semi-dry friction working conditions with limited lubrication. Regularly arranged circular depressions are formed on the sliding surface, which are filled with sufficient lubricant once during assembly. The sliding material consists of polyacetal anchored in porous bronze on a sintered steel substrate.
The KX bimetallic strip has a 0.25 mm thick layer of polyacetal over the bronze interlayer so that it can be machined if required. It has good conformability, hence its resistance to edge pressures, but is not suitable for dry work.
The coefficient of friction is low when initially lubricated with grease and increases thereafter. When the sliding life of the KX bimetallic belt is not sufficient with the basic lubricant supply, it can be increased by repeated relubrication. KX bimetallic belt products have excellent sliding properties.
The operating temperature range is from -40 to +110°C, short term up to +130°C.
The POM bushings are equivalent to the bushings marked PM...,PCM...M, PAP...P20, GLY.AB..., MX..., SF-2...,

POM bushing size chart
The POM-based sleeve bearing, also called POM bushing, boundary lubricated bearing, oil-free bearing, dry bearing, POM bearing and POM coated dry sleeve. It has a similar material structure with dowels. The difference lies in the POM coated layer.
Yellow POM composite bushing is a standard item of our company. This type self-lubricating bearing has same material structure with other bushing.
1. POM 0.3~0.5mm.
2. Porous bronze 0.2~0.3mm.
3. Steel backing 0.4~2.2mm.
4. Copper plating 0.008mm.
